Abstract
A polymer or copolymer of weight average molecular weight from 1000 to 200,000 prepared from an ethylenically unsaturated ester and containing from 0.1 to 50% by weight of polyoxyalkylene groups of molecular weight from 100 to 5000 is used to improve the cold flow properties of liquid hydrocarbon especially distillate fuels and has improved interaction with other additives.
